Mr. Charles G. Leland, in his work on Practical Education, distinctly insists on the utility, indeed the paramount importance, of a sound and practical rudimentary training, whether in connection with elementary or more advanced technical education. This is becoming daily and increasingly apparent to those who, in their care and training of the young of both sexes, are guided by reason and common sense. Failing such a basis, it is obvious that no process of later cramming is likely to produce equally successful and permanently beneficial results. This series of manuals on The Minor Arts and Industries is designed on the lines thus laid down. It will be found that each handbook presents the subject with which it deals in a thoroughly popular and practical manner; that the lessons carry the student on his road step by step from the simplest elements to the point where the most advanced works fitly find their place in his course of study; in short, the greatest pains have been taken to insure a thorough mastery of the rudiments of each subject, and so clearly to state each lesson, illustrating it where necessary by plans and drawings, that even very young children may be interested in and trained to practical work. On similar grounds the self-taught student will find these manuals an invaluable aid to his studies.
